RASI objectives

Regional Air-Sea Interactions (a DISCOVER MEaSUREs tool)

  • Develop automated mining solution to

extract gap wind and SST (sea surface temperature) events using microwave products.

  • Generate gap wind and SST event

climatology using the automated algorithms.

  • Distribute event climatology to users through

an interactive web application.

Regional Air-Sea Interactions (RASI) in Central America

Ocean cooling on MW OISST product 01/22/2001

Strong gap wind over Gulf of Tehuantepec was observed from morning pass of QuikScat wind field on 01/22/2001. Coastal upwelling occurs when strong gap winds trigger intense vertical mixing

  • f the ocean. Warm surface water was

pushed by wind jet away from the coast and deep cold water and nutrients rise to the surface.

RASI Climatology Impacts/Uses

  • Gap wind-triggered air–

sea interactions may have long-lasting effects in both the ocean and atmosphere (Xie et al. 2005).

  • Documentation of this
  • rographically-induced air-

sea coupled phenomena can serve as a benchmark for accurately evaluating coupled atmospheric-

  • cean models (Xie et al.

2005).

  • This air-sea interaction

process significantly changes the regional nutrient distribution and local ecological environment.

  • 10-year climatology of

gale- and storm-force Tehuano wind events were produced using 25 km QuikSCAT wind product (Brennal et al. 2010).

(CCMP) ocean surface winds product

  • Combining wind measurements

from SeaWinds, AMSR-E, TMI, SSM/I and SSMIS on DMSP using a 4D variational analysis model.

  • Global high resolution (25 km)
  • ver ocean surface.
  • 6-hourly gridded data at 0, 6, 12

and 18 Z.

  • Data available from 1987 –

2011.

  • Microwave Optimally Interpolated Sea

Surface Temperatures (OISST)

  • Daily SST data at 0.25 degree

resolution.

  • Data available 1998 to present
  • Event climatology currently covers 1998

to 2011

Discussion

Microwave Data

  • What datasets can be added to supplement

the microwave holdings?

  • What is your preferred data format?
  • How can we improve metadata collection?
  • What pertinent information should be

added to user guides? Tools

  • What tools are needed to better serve

these datasets?

  • Would custom data analysis be useful for
  • ther cases?
  • What other data services would be useful?

Please contact GHRC User Services for any help or questions ghrcdaac@itsc.uah.edu
